Tetraphenylpentalenide organolanthanide complexes

Abstract

The D2h symmetrical 1,3,4,6-tetraphenylpentalenide is an excellent ligand for the stabilisation of strongly coloured bis(pentalenide) sandwich LnIII complexes. These easily accessible compounds complement previously reported lanthanide sandwich organometallics and provide new opportunities to understand the roles of the f-orbitals in electronic structures.
